An interesting thing happened to me in the word Nisan here in this Megilla today. As I was finishing the Samech, on the very last point of connecting it in its top right hand corner, I touched the Koz RT of the Yud. There is no Shinui Tzura so I would usually be able to be Gorer and destroy everything in the Samech from the that point on. Since the point of Negia is also the point of finishing the letter what do I need to do? Can I just separate them? The real question is what do we consider as happening first, and if it happens at the same time then do I need to Mevatel Ha'Ot (since it happens Be'Et Ketiva)?

1)  I widened the gag of a chof pshutah (from the word lecha beow) to make it wider because there was more than 3 yudin between the words. Then , in order to make the chof pshutah more perfect, I attempted to thicken the regel with my rapidograph, only I started a bit too wide and ended up making a gap. see pic below. I am 99% certain that this would not be a shinuy tzurah in any way, however I wouldn't mind a second opinion before I fill it in and complete the tikun, which should look fine once it's complete 2) The vav from the word vechol above... 3) Finally, I have a house that has a very unique entrance way, when you walk down the walkway there are 3 metallic "archways" which are not there for support, but more for design. since it is in essence a mashkof and you walk through it, would they require a mezuzah? Its on the main walkway leading to the front door.
